What are conspiracy theories? And what, if anything, is epistemically wrong with them? I offer an account on which conspiracy theories are a unique way of holding a belief in a conspiracy. Specifically, I take conspiracy theories to be self-insulating beliefs in conspiracies. On this view, conspiracy theorists have their conspiratorial beliefs in a way that is immune to revision by counter-evidence. I argue that conspiracy theories are always irrational. Although conspiracy theories involve an expectation to encounter some seemingly (...) disconfirming evidence (allegedly planted by the conspirators), resistance to all counter- evidence cannot be justified on these grounds.

Conspiracy theories should be neither believed nor investigated - that is the conventional wisdom. I argue that it is sometimes permissible both to investigate and to believe. Hence this is a dispute in the ethics of belief. I defend epistemic ‘oughts’ that apply in the first instance to belief-forming strategies that are partly under our control. I argue that the policy of systematically doubting or disbelieving conspiracy theories would be both a political disaster and the epistemic equivalent of self-mutilation, since (...) it leads to the conclusion that history is bunk and the nightly news unbelievable. In fact (of course) the policy is not employed systematically but is only wheeled on to do down theories that the speaker happens to dislike. I develop a deductive argument from hard-to-deny premises that if you are not a ‘conspiracy theorist’ in my anodyne sense of the word then you are an ‘idiot’ in the Greek sense of the word, that is, someone so politically purblind as to have no opinions about either history or public affairs. The conventional wisdom can only be saved (if at all) if ‘conspiracy theory’ is given a slanted definition. I discuss some slanted definitions apparently presupposed by proponents of the conventional wisdom (including, amongst others, Tony Blair) and conclude that even with these definitions the conventional wisdom comes out as deeply unwise. I finish up with a little harmless fun at the expense of David Aaronvitch whose abilities as a rhetorician and a popular historian are not perhaps matched by a corresponding capacity for logical thought.

There’s a certain pleasure in fantasizing about possessing knowledge, especially possessing secret knowledge to which outsiders don’t have access. Such fantasies are typically a source of innocent entertainment. However, under the right conditions, fantasies of knowledge can become epistemically dangerous, because they can generate illusions of genuine knowledge. I argue that this phenomenon helps to explain why some people join and eventually adopt the beliefs of epistemic communities who endorse seemingly bizarre, outlandish claims, such as extreme cults and online conspiracy (...) theory groups. It can be difficult to grasp how members of such groups come to believe the theories they endorse. I argue that one route to such beliefs is via deep absorption in fantasies of knowledge, which can lead entire groups to become collectively detached from reality. (shrink)

[To readers: Please consider visiting the journal's website to read this work.] In spite of referring to the human tendency to "breath together" or share the same spirit, the word "conspire" has developed a negative connotation in contemporary society, specifically as it pertains to theorizing about conspiracies as a result of the human proclivity to recognize patterns recognition and coalesce common themes amongst those with shared perceptions into something resembling a unified narrative. This proclivity has only become more pronounced (...) with the dawn of the Internet age, and as a result, the tendency to assume the actuality of certain conspiracies and insulate ourselves from viable, competing ideas has led to a series of microenvironments not dissimilar from those that allow for the proliferation of cancerous cells in the human body. In this article, I draw out the analogy between cancer and conspiracy theorizing in order to present readers with a clearer picture of the deleterious effects of the contemporary phenomena such as unbridled political polarization and the effect of sociopolitical news coverage presented by low-correlation outlets, otherwise known as "echo chambers.".

Conspiracy theories are frequently described as a threat to democracy and conspiracy theorists portrayed as epistemically or morally unreasonable. If these characterizations are correct, then it may be the case that reasons stemming from conspiracy theorizing threaten the legitimizing function of democratic deliberation. In this paper, I will argue the opposite. Despite the extraordinary epistemic and morally unreasonable claims made by some conspiracy theorists, belief in conspiracy theories is guided by internal epistemic norms inherent in believing. By utilizing the insights (...) of the Peircean epistemic defense formulated by Cheryl Misak and Robert Talisse, I take it that these epistemic norms implicitly commit the theorist to an open democratic society. (shrink)

This paper seeks to carve out a distinctive category of conspiracy theorist, and to explore the process of becoming a conspiracy theorist of this sort. Those on whom I focus claim their beliefs trace back to simply trusting their senses and experiences in a commonsensical way, citing what they take to be authoritative firsthand evidence or observations. Certain flat Earthers, anti-vaxxers, and UFO conspiracy theorists, for example, describe their beliefs and evidence this way. I first distinguish these conspiracy theorists by (...) contrasting them with another group that has recently received a lot of attention from the media, philosophers, and academics more broadly. I then dig more deeply into the nature of these conspiracy theorists’ epistemic self-understanding, in order to give an account of the process by which one becomes such a conspiracy theorist. I conclude with some takeaways and implications: first, I explore the implications of my account for whether these conspiracy theorists’ beliefs are rational; then, I argue that my account has practical takeaways about counteracting beliefs in misinformation, since strategies appropriate to this kind of conspiracy theorist may not be the same ones that are appropriate for other kinds. (shrink)

Critics of conspiracy theories often charge that such theories are implausible because conspiracies of the kind they allege tend to fail. Thus, according to these critics, conspiracy theories that have been around for a while would have been, in all likelihood, already exposed if they had been real. So, they reason, they probably are not. In this article, I maintain that the arguments in support of this view are unconvincing. I do so by examining a list of four sources (...) recently cited in support of the claim that conspiracies tend to fail. I pay special attention to two of these sources, an article by Brian Keeley, and, especially, an article by David Grimes, which is perhaps the single “best” article in support of the idea that conspiracies tend to fail. That is, it offers the most explicit and elaborate attempt to establish this view. Further, that article has garnered significant (uncritical) attention in the mainstream press. I argue that Grimes's argument does not succeed, that the common assertion that conspiracies tend to fail remains poorly supported, and that there are good reasons to think that at least some types of conspiracies do not tend to fail. (shrink)

Conspiracy theories and conspiracy theorists have been accused of a great many sins, but are the conspiracy theories conspiracy theorists believe epistemically problematic? Well, according to some recent work, yes, they are. Yet a number of other philosophers like Brian L. Keeley, Charles Pigden, Kurtis Hagen, Lee Basham, and the like have argued ‘No!’ I will argue that there are features of certain conspiracy theories which license suspicion of such theories. I will also argue that these features only license a (...) limited suspicion of these conspiracy theories, and thus we need to be careful about generalising from such suspicions to a view of the warrant of conspiracy theories more generally. To understand why, we need to get to the bottom of what exactly makes us suspicious of certain conspiracy theories, and how being suspicious of a conspiracy theory does not always tell us anything about how likely the theory in question is to be false.

9/11 was an inside job. The Holocaust is a myth promoted to serve Jewish interests. The shootings at Sandy Hook Elementary School were a false flag operation. Climate change is a hoax perpetrated by the Chinese government. These are all conspiracy theories. A glance online or at bestseller lists reveals how popular some of them are. Even if there is plenty of evidence to disprove them, people persist in propagating them. Why? Philosopher Quassim Cassam explains how conspiracy theories are different (...) from ordinary theories about conspiracies. He argues that conspiracy theories are forms of propaganda and their function is to promote a political agenda. Although conspiracy theories are sometimes defended on the grounds that they uncover evidence of bad behaviour by political leaders, they do much more harm than good, with some resulting in the deaths of large numbers of people. There can be no clearer indication that something has gone wrong with our intellectual and political culture than the fact that conspiracy theories have become mainstream. When they are dangerous, we cannot afford to ignore them. At the same time, refuting them by rational argument is difficult because conspiracy theorists discount or reject evidence that disproves their theories. As conspiracy theories are so often smokescreens for political ends, we need to come up with political as well as intellectual responses if we are to have any hope of defeating them. (shrink)

Conspiracy theories are often portrayed as unwarranted beliefs, typically supported by suspicious kinds of evidence. Yet contemporary work in Philosophy argues provisional belief in conspiracy theories is at the very least understandable---because conspiracies occur---and that if we take an evidential approach, judging individual conspiracy theories on their particular merits, belief in such theories turns out to be warranted in a range of cases. -/- Drawing on this work, I examine the kinds of evidence typically associated with conspiracy theories, and (...) show how the so-called evidential problems with conspiracy theories are also problems for the kinds of evidence put forward in support of other theories. As such, if there is a problem with the conspiracy theorist's use of evidence, it is one of principle: is the principle which guides the conspiracy theorist's use of evidence somehow in error? I argue that whatever we might think about conspiracy theories generally, there is no prima facie case for a scepticism of conspiracy theories based purely on their use of evidence. (shrink)

The philosopher Quassim Cassam has described a concept called ‘Conspiracy Theories’ (capitalized) that includes several ‘special features’ that distinguish such theories from other theories positing conspiracies. Conspiracy Theories, he argues, are unlikely to be true. Indeed, he implies that they are, as a class of ideas, so unlikely to be true that we are justified in responding to them by criticizing the ideology they are (presumed to be) associated with, rather than engaging them solely on their individual epistemic merits. (...) This article argues that Cassam’s ‘special features’ are ambiguous. Under some interpretations, they are not epistemically problematic. Under other interpretations, they do not fairly describe many of the theories Cassam treats as examples of Conspiracy Theories. In the end, there seems to be no interpretation of these features that would justify the inference that theories Cassam treats as Conspiracy Theories, including JFK Conspiracy Theories, can be reasonably dismissed on account of having these features.

I argue that that an influential strategy for understanding conspiracy theories stands in need of radical revision. According to this approach, called ‘generalism’, conspiracy theories are epistemically defective by their very nature. Generalists are typically opposed by particularists, who argue that conspiracy theories should be judged case-by-case, rather than definitionally indicted. Here I take a novel approach to criticizing generalism. I introduce a distinction between ‘Dominant Institution Conspiracy Theories and Theorists’ and ‘Non-Dominant Institution Conspiracy Theories and Theorists’. Generalists uncritically center (...) the latter in their analysis, but I show why the former must be centered by generalists’ own lights: they are the clearest representatives of their views, and they are by far the most harmful. Once we make this change in paradigm cases, however, various typical generalist theses turn out to be false or in need of radical revision. Conspiracy theories are not primarily produced by extremist ideologies, as generalists typically claim, since mainstream, purportedly non-extremist political ideologies turn out to be just as, if not more responsible for such theories. Conspiracy theories are also, we find, not the province of amateurs: they are often created and pushed by individuals widely viewed as experts, who have the backing of our most prestigious intellectual institutions. While generalists may be able to take this novel distinction and shift in paradigm cases on board, this remains to be seen. Subsequent generalist accounts that do absorb this distinction and shift will look radically different from previous incarnations of the view. (shrink)

Conspiracy theories are a popular topic of conversation in everyday life but are often frowned upon in academic discussions. Looking at the recent spate of philosophical interest in conspiracy theories, The Philosophy of Conspiracy Theories looks at whether the assumption that belief in conspiracy theories is typically irrational is well founded.

This paper presents the results of two corpus studies investigating the discourse surrounding conspiracy theories and genuine theories. The results of these studies show that conspiracy theories lack the epistemic and scientific standing characteristic of theories more generally. Instead, our findings indicate that conspiracy theories are spread in a manner that resembles the dissemination of rumors and falsehoods. Based on these empirical results, we argue that it is time for both re-engineering conspiracy theory and for relabeling "conspiracy theory". We propose (...) relabelling conspiracy theories as either "conspiracy stories" or "conspiracy narratives" to more accurately convey their true nature. (shrink)

This paper develops a new kind of approach to conspiracy theories – a procedural approach. This approach promises to establish that belief in conspiracy theories is rationally criticisable in general. Unlike most philosophical approaches, a procedural approach does not purport to condemn conspiracy theorists directly on the basis of features of their theories. Instead, it focuses on the patterns of thought involved in forming and sustaining belief in such theories. Yet, unlike psychological approaches, a procedural approach provides a rational critique (...) of conspiracist thought patterns. In particular, it criticises these thought patterns for failing to conform to procedures prescribed by reason. The specific procedural approach that I develop takes its cue from the Kantian notion that reason must be used self-critically. I tentatively suggest that conspiracy theorists fail to engage in the relevant sort of self-critique in at least three ways: they do not critically examine their own motivations, they avoid looking at matters from the point of view of others, and they fail to reflect on the limits of human knowledge. (shrink)

A remarkable feature of the philosophical work on conspiracy theory theory has been that most philosophers agree there is nothing inherently problematic about conspiracy theories (AKA the thesis of particularism). Recent work, however, has challenged this consensus view, arguing that there really is something epistemically wrong with conspiracy theorising (AKA generalism). Are particularism and generalism incompatible? By looking at just how much particularists and generalists might have to give away to make their theoretical viewpoints compatible, I will argue that particularists (...) can accept many of the concerns that motivate generalism because generalism can never be about ‘all’ conspiracy theories without being either ahistorical or apolitical. In the end generalist critiques are best seen as useful guidelines or considerations for the appraising of particular conspiracy theories. (shrink)

The epistemological literature on conspiracy theory has established that strict generalism about conspiracy theories is untenable. This chapter argues, however, that this does not license a move to naive or strict particularism. Rather, any consideration of specific conspiracy claims needs to address conspiracy theory not simply as a formal category of explanation, but as a distinctive social practice, with a history and explanatory repertoire that can give us important, if defeasible, reasons for rejecting at least some such types of claim. (...) These reasons are not merely epistemic. The moral costs of participating in such practices, and of levelling conspiracy accusations in general, generate corresponding ethical requirements for reticence about entertaining conspiracy theories. This doesn’t mean we can retreat to generalism; but it does mean particularism must be governed by a reluctance that, in practice, will rule out a great many conspiracy theory claims as candidates for serious investigation. (shrink)

Scholarly treatments of conspiracy theories and of rumours tend to follow a similar pattern. In both cases they usually begin by presupposing that the phenomena in question (conspiracy theories or rumours) should not be believed. They then seek to explain the puzzling fact that many people (though not of course the author or reader) are nonetheless inclined to believe them. I will argue that this is all wrong. Neither rumours nor conspiracy theories deserve their bad reputation. I will also argue (...) that rumours and conspiracy theories have a bad reputation because of a certain kind of propaganda. Not all propaganda is objectionable, but this propaganda is objectionable, because it is anti-democratic propaganda. (shrink)

There has been much interest in conspiracy theories (CTs) amongst philosophers in recent years. The aim of this paper will be to apply some of the philosophical research to issues in political theory. I will first provide an overview of some of the philosophical discussions about CTs. While acknowledging that particularism is currently the dominant position in the literature, I will contend that the ‘undue scepticism problem’, a modified version of an argument put forward by Brian Keeley, is an important (...) general objection to many CTs. This in turn leads to some substantial conclusions for liberal political philosophy, as the undue scepticism problem sets up a strong argument against non-liberal alternatives to liberal thought. I shall argue that we are justified in having far more doubt about the reliability of official sources in non-liberal societies, and it is legitimate to be more sceptical about claims designed to bolster non-liberal politics. Moreover, because scepticism is often more warranted in non-liberal societies, this may provide the possibility for the state to be stable, even if it is highly tyrannical or ineffective. These considerations are not intended to be decisive, but raise unresolved questions about the viability of non-liberal politics. (shrink)

Napolitano (2021) argues that the Minimalist Account of conspiracy theories—i.e., which defines conspiracy theories as explanations, or theories, about conspiracies—should be rejected. Instead, she proposes to define conspiracy theories as a certain kind of belief—i.e., an evidentially self-insulated belief in a conspiracy. Napolitano argues that her account should be favored over the Minimalist Account based on two considerations: ordinary language intuitions and theoretical fruitfulness. I show how Napolitano’s account fails its own purposes with respect to these two considerations and (...) so should not be favored over the Minimalist Account. Furthermore, I propose that the Minimalist Account is the best conception of ‘conspiracy theory’ if we share Napolitano’s goal of advancing the understanding of conspiracy theories. (shrink)

Why do people endorse conspiracy theories? There is no single explanation: different people have different attitudes to the theories they say they believe. In this paper, I argue that for many, conspiracy theories are serious play. They’re attracted to conspiracy theories because these theories are engaging: it’s fun to entertain them (witness the enormous number of conspiracy narratives in film and TV). Just as the person who watches a conspiratorial film suspends disbelief for its duration, so many conspiracy theorists do (...) not believe the theories they endorse; rather, they suspend disbelief in them. I argue that the serious play hypothesis explains some characteristic features of conspiracy theories, such as their gamification and the kind of relationship they have to evidence. (shrink)

While engaging in rich discussion, Conspiracy Theories analyzes current arguments and evidence while providing real-world examples so students can contextualize and visualize the debates. Each chapter addresses important current questions, provides conceptual tools, defines important terms, and introduces the appropriate methods of analysis.

Quassim Cassam has argued that psychological and epistemological analyses of conspiracy theories threaten to overlook the political nature of such theories. According to Cassam, conspiracy theories are a form of political propaganda. I develop a limited critique of Cassam's analysis.This paper advances two core theses. First, acceptance of conspiracy theories requires a rejection of epistemic authority that renders conspiracy theorists susceptible to co-option by certain political programs while insulating such programs from criticism. I argue that the contrarian nature of conspiracy (...) theories partially accounts for the prominence of such theories in populist movements.Second, the contrarian nature of conspiracy theories partially accounts for their attractiveness, especially among those to whom populism already appeals. I argue that for those who resent what appears from their perspective as the shaping of the epistemic landscape by alien perspectives, conspiracy theorizing may facilitate the reassertion of epistemic autonomy. (shrink)

Recent philosophical treatment of conspiracy theories supposes them all to be explanatory, thus overlooking those conspiracy theories whose major purpose is the assertion of ‘hidden facts’ rather than explanation of accepted facts. I call this variety of non-explanatory conspiracy theories “counterfact theories”. In this paper, through the use of examples, including the Obama birth certificate conspiracy theory, I uncover the distinctive reasoning pattern and dialectical strategy of counterfact theories, highlighting their epistemic flaws.

Abstract Conspiracy theories should be neither believed nor investigated - that is the conventional wisdom. I argue that it is sometimes permissible both to investigate and to believe. Hence this is a dispute in the ethics of belief. I defend epistemic “oughts” that apply in the first instance to belief-forming strategies that are partly under our control. But the beliefforming strategy of not believing conspiracy theories would be a political disaster and the epistemic equivalent of selfmutilation. I discuss several variations (...) of this strategy, interpreting “conspiracy theory” in different ways but conclude that on all these readings, the conventional wisdom is deeply unwise. (shrink)

Presumably authoritative sources, such as social scientists who study conspiracy theorists, are generally expected to be logically rigorous, intellectually honest, and unbiased. This chapter suggests that this expectation may not always be justified. Specifically, it exposes a number of significant problems in an attempt by a group of social scientists to defend the (ostensibly) scientific study of conspiracy theorists. First, they misrepresent their own previously stated intentions. Second, they misrepresent a critique of those intentions. Third, they fail completely in their (...) attempt to show that, regarding the inappropriate pathologizing of conspiracy theorists, their critics are guilty as they are. Fourth, they cite seriously flawed studies as though they offered robust findings. And fifth, their criticism of a central distinction, between “generalist” and “particularist” approaches, is based on a misunderstanding. This raises troubling questions: How can we to have confidence in a program of study undertaken, in part, by scientists who get so much wrong? And, to what degree is this an isolated problem?

Although people who endorse conspiracy theories related to medicine often have negative attitudes toward particular health care measures and may even shun the healthcare system in general, conspiracy theories have received rather meager attention in bioethics literature. Consequently, and given that conspiracy theorizing appears rather prevalent, it has been maintained that there is significant need for bioethics debate over how to deal with conspiracy theories. While the proposals have typically focused on the effects that unwarranted conspiracy theories have in the (...) public health context, Nathan Stout's recent argument concentrates on the impacts that such theories have at the individual level of clinical decision‐making. In this article, I maintain that duly acknowledging the impacts of conspiracy theories that raise Stout's concern does not require bioethics debate over the proper response to the influence of conspiracy theories in healthcare. Having evaluated two possible objections, I conclude by briefly clarifying the purported import of the response to Stout. (shrink)

Patrick Stokes has argued that although many conspiracy theories are true, we should reject the policy of particularism (that is, the policy of investigating conspiracy theories if they are plausible and believing them if that is what the evidence suggests) and should instead adopt a policy of principled skepticism, subjecting conspiracy theories – or at least the kinds of theories that are generally derided as such – to much higher epistemic standards than their non-conspiratorial rivals, and believing them only if (...) they are proven up to the hilt. The reason is that although some conspiracy theories are true (or otherwise epistemically kosher) there is a widespread practice of conspiracy theorizing which leads to the social acceptance of conspiracy theories which (much like Lord Byron) are mad, bad and dangerous to ‘know’, leading to radically false beliefs about the natural and political worlds (for instance to Trump’s claim that Global Warming is a ‘Chinese Hoax’). Thus Stokes is a defender of the epistemic status quo in which the punditocracy routinely dismisses and sneers at ‘conspiracy theories’, simply because they are conspiracy theories, whilst admitting sotto voce that once in a blue moon there are some conspiracy theories that are true. It is just the he would prefer the epistemic policy of the punditocracy to be the policy of the populace at large. Stokes seems to be suggesting that although particularism looks like a sensible epistemic policy (and might indeed be the correct policy in an ideal world), if it were put into practice at the level of public debate it would give a specious air of plausibility to many false and dangerous conspiracy theories with pernicious social effects. I reply that the actual moral costs of conspiracy ‘skepticism’ (as it is currently practiced) exceed the likely costs of particularism, especially if it is informed by some sensible heuristics, ruling out some conspiracy theories as crazy and ruling in others as relatively sane. For the conspiracy ‘skepticism’ as currently practiced is highly selective, pouring scorn and contempt on conspiracy theories which threaten current elites whilst giving the conspiratorial concoctions of those elites something close to a free pass.

Conspiracy theories have a bad reputation. This is especially true in the academy and in the media. Within these institutions, to describe someone as a conspiracy theorist is often to imply that his or her views should not be taken seriously. Perhaps this accounts for the fact that philosophers have tended to ignore the topic, despite the enduring appeal of conspiracy theories in popular culture. Recently, however, some philosophers have at least treated conspiracy theorists respectfully enough to try to articulate (...) where they go wrong.I begin this paper by clarifying the nature of conspiracy theories. I then argue against some recent critiques of conspiracy theories. Many criticisms of conspiracy theories are unfounded. I also argue that unwillingness to entertain conspiracy theories is an intellectual and moral failing. I end by suggesting an Aristotelian approach to the issue, according to which the intellectual virtue of realism is a golden mean between the intellectual vices of paranoia and naivety. (shrink)

In an article based on a recent address to the Royal Institute of Philosophy, Keith Harris has argued that there is something epistemically wrong with conspiracy theorizing. Although he finds “standard criticisms” of conspiracy theories wanting, he argues that there are three subtle but significant problems with conspiracy theorizing: It relies on an invalid probabilistic version of modus tollens. It involves a problematic combination of both epistemic virtues and vices. And it lacks an adequate basis for trust in its information (...) sources. In response to Harris, this article argues that, like previous criticisms, these criticisms do little to undermine conspiracy theorizing as such. And they do not give us good reasons to dismiss any particular conspiracy theory without consideration of the relevant evidence. (shrink)

In this paper I interrogate the notion of `debunking conspiracy theories’, arguing that the term `debunk’ carries with it pejorative implications, given that the verb `to debunk’ is commonly understood as `to show the wrongness of a thing or concept’. As such, the notion of `debunking conspiracy theories’ builds in the notion that such theories are not just wrong but ought to be shown as being wrong. I argue that we should avoid the term `debunk’ and focus on investigating conspiracy (...) theories. Looking at recent research work in epistemology on conspiracy theory, I argue that the best way to avoid talk of `debunking’ conspiracy theories is by working with a non-pejorative definition of `conspiracy theory’, and forming communities of inquiry which allow us to investigate the warrant of such theories without the prejudice associated with working with a pejorative definition.

A response to Lee Basham's 'The Need for Accountable Witnesses: A Reply to Dentith'.

Conspiracy theories are often portrayed as unwarranted beliefs, typically supported by suspicious kinds of evidence. Yet contemporary work in Philosophy argues provisional belief in conspiracy theories is—at the very—least understandable (because conspiracies occur) and if we take an evidential approach—judging individual conspiracy theories on their particular merits—belief in such theories turns out to be warranted in a range of cases. Drawing on this work, I examine the kinds of evidence typically associated with conspiracy theories, showing that the evidential problems (...) typically associated with conspiracy theories are not unique to such theories. As such, if there is a problem with the conspiracy theorist’s use of evidence, it is one of principle: is the principle which guides their use of evidence somehow in error? I argue that whatever we might think about conspiracy theories generally, there is no prima facie case for a scepticism of conspiracy theories based purely on their use of evidence. (shrink)

The contributors to this volume argue that whilst there is a commonplace superstition conspiracy theories are examples of bad beliefs (and that the kind of people who believe conspiracy theories are typically irrational), many conspiracy theories are rational to believe: the members of the Dewey Commission were right to say that the Moscow Trials of the 1930s were a sham; Woodward and Bernstein were correct to think that Nixon was complicit in the conspiracy to deny any wrongdoing in the Watergate (...) Hotel break in; and if we either accept the terrorist events of 9/11 were committed by Al-Qaeda, or that the Bush Administration was responsible, then it seems we are endorsing some theory about a conspiracy to commit an act of terror on American soil. As such, there is no reason to reject conspiracy theories sui generis. This volume challenges the prima facie that conspiracy theories are irrational beliefs, arguing that we should treat conspiracy theories and the phenomena of conspiracy theories seriously. It presents fresh perspectives from the wider philosophical, sociological and psychological community on what is becoming an issue of increasing relevance in our time. (shrink)

In the social science literature, conspiracy theories are commonly characterized as theories positing a vast network of evil and preternaturally effective conspirators, and they are often treated, either explicitly or implicitly, as dubious on this basis. This characterization is based on Richard Hofstadter’s famous account of ‘the paranoid style’. However, many significant conspiracy theories do not have any of the relevant qualities. Thus, the social science literature provides a distorted account of the general category ‘conspiracy theory’, conflating it with a (...) subset of that category that encourages unfairly negative evaluations of conspiracy theories. Generally, when evaluating theories, one should focus on the most plausible versions; the merit of a theory is independent of the existence of less plausible versions of it. By ignoring this and glossing over important distinctions, many academics, especially in the social sciences, have misclassified many conspiracy theories and in doing so have contributed to an epistemically unfair depiction of them. Further, even theories that genuinely fit the description of ‘the paranoid style’ cannot be completely dismissed on that basis. All conspiracy theories ought to be judged on the totality of their individual merits. (shrink)

Conspiracy theories have a bad reputation. In the past, most philosophers have ignored the topic, vaguely supposing that conspiracy theories are obviously irrational and that they can be easily dismissed. The current philosophical interest in the subject results from a realisation that this is not so. Some philosophers have taken up the challenge of identifying and explaining the flaws of conspiracy theories. Other philosophers have argued that conspiracy theories do not deserve their bad reputation, and that conspiracy theorists do not (...) deserve their reputation for irrationality. This book represents both sides of this important debate. Aimed at a broad philosophical community, including epistemologists, political philosophers, and philosophers of history. It represents a significant contribution to the growing interdisciplinary debate about conspiracy theories. (shrink)

I argue that ‘conspiracy theory’ and ‘conspiracy theorist’ as commonly employed are ‘tonkish’ terms (as defined by Arthur Prior and Michael Dummett), licensing inferences from truths to falsehoods; indeed, that they are mega-tonkish terms, since their use is governed by different and competing sets of introduction and elimination rules, delivering different and inconsistent results. Thus ‘conspiracy theory’ and ‘conspiracy theorist’ do not have determinate extensions, which means that generalizations about conspiracy theories or conspiracy theorists do not have determinate truth-values. Hence (...) conspiracy theory theory – psychological or social scientific research into conspiracy theorists and what is wrong with them – is often about as intellectually respectable as an enquiry into bastards and what makes them so mean.

Abstract It is widely believed that to be a conspiracy theorist is to suffer from a form of irrationality. After considering the merits and defects of a variety of accounts of what it is to be a conspiracy theorist, I draw three conclusions. One, on the best definitions of what it is to be a conspiracy theorist, conspiracy theorists do not deserve their reputation for irrationality. Two, there may be occasions on which we should settle for an inferior definition which (...) entails that conspiracy theorists are after all irrational. Three, if and when we do this, we should recognise that conspiracy theorists so understood are at one end of a spectrum, and the really worrying form of irrationality is at the other end. (shrink)

As the end of the Millennium approaches, conspiracy theories are increasing in number and popularity. In this short essay, I offer an analysis of conspiracy theories inspired by Hume's discussion of miracles. My first conclusion is that whereas Hume can argue that miracles are, by definition, explanations we are not warranted in believing, there is nothing analytic that will allow us to distinguish good from bad conspiracy theories. There is no a priori method for distinguishing warranted conspiracy theories (say, those (...) explaining Watergate) from those which are unwarranted (say, theories about extraterrestrials abducting humans). Nonetheless, there is a cluster of characteristics often shared by unwarranted conspiracy theories. An analysis of the alleged explanatory virtues of unwarranted conspiracies suggests some reasons for their current popularity, while at the same time providing grounds for their rejection. Finally, I discuss how conspiracy theories embody an anachronistic world-view that places the contemporary zeitgeist in a clearer light. (shrink)

Conspiracy Theories The term “conspiracy theory” refers to a theory or explanation that features a conspiracy among a group of agents as a central ingredient.

In much of the current academic and public discussion, conspiracy theories are portrayed as a negative phenomenon, linked to misinformation, mistrust in experts and institutions, and political propaganda. Rather surprisingly, however, philosophers working on this topic have been reluctant to incorporate a negatively evaluative aspect when either analyzing or engineering the concept conspiracy theory. In this paper, we present empirical data on the nature of the concept conspiracy theory from five studies designed to test the existence, prevalence and exact form (...) of an evaluative dimension to the ordinary concept conspiracy theory. These results reveal that, while there is a descriptive concept of conspiracy theory, the predominant use of conspiracy theory is deeply evaluative, encoding information about epistemic deficiency and often also derogatory and disparaging information. On the basis of these results, we present a new strategy for engineering conspiracy theory to promote theoretical investigations and institutional discussions of this phenomenon. We argue for engineering conspiracy theory to encode an epistemic evaluation, and to introduce a descriptive expression—such as ‘conspiratorial explanation’—to refer to the purely descriptive concept conspiracy theory.

Are conspiracy theorists epistemically vicious? That is the conventional wisdom. It has distinguished supporters, including Quassim Cassam, Cass Sunstein and Adrian Vermeule. For me, a trait is an epistemic virtue if leads to the discovery of salient truths and the avoidance of pernicious falsehoods, and an epistemic vice the contrary. As such epistemic virtues and vices are role‐relative, context‐relative and end‐relative. I argue that that it is not necessarily or even usually vicious to be a conspiracy theorist, even if we (...) restrict the conspiracies in question to conspiracies on the part of Western government agencies, the reason being that many such theories are now known to be true. Finally I contend that the policy suggested by some polemicists of systematic skepticism towards conspiracy theories would be intellectually suicidal and hence vicious. (shrink)

Conspiracy theories have historically had a bad reputation, with many philosophers dismissing the topic as irrational. Current philosophical debate has challenged this stance, suggesting that these theories do not deserve their bad reputation. This book represents both sides of the debate. Aimed at a broad philosophical community, including epistemologists, political philosophers, and philosophers of history, this book is a significant contribution to the growing interest in conspiracy theories.

The popularity of conspiracy theories poses a clear challenge for contemporary liberal democracies. Conspiracy theories undermine rational debate, spread dangerous falsehoods and threaten social cohesion. However, any possible public policy response, which would try to contain their spread, needs to respect the liberal commitment to protect pluralism and free speech. A successful justification of such a policy must therefore: 1) clearly identify the problematic class of conspiracy theories; and 2) clarify the grounds on which the state is justified in acting (...) against them. This article argues that the prevailing epistemic approaches to conspiracy theorizing cannot fulfil these criteria. Defining conspiracy theories by their flaws in reasoning, questionable coherence or factual mistakes can neither sharply distinguish problematic conspiracy theories from other, non-problematic worldviews nor justify state action. Thus, we propose to understand conspiracy theories through their ethical unreasonableness. We hold that containment of conspiracy theories is justifiable insofar as they undermine the liberal-democratic ideals of mutual respect, freedom and equality. We then show that such ‘ethical’ criteria for conspiracy theories can be sufficiently robust and clear-cut so that they can serve as a useful guide for public policy. (shrink)

One issue within conspiracy theory theory is whether, or to what extent, our central concept – – should map on to the common, lay sense of the term. Some conspiracy theory theorists insist that we use the term as everyday people use it. So, for example, if the term has a pejorative connotation in everyday parlance, then academic work on the concept should reflect that. Other conspiracy theory theorists take a more revisionist approach, arguing instead that while their use of (...) the theoretical concept should bear some relation to its use in natural language, it need not follow it subserviently. I argue that elements of this debate mirror related debates that were prominent in the philosophy of mind in the 1980s over folk psychology and eliminative materialism (debates that continue today, such as within the philosophy of perception and theories over how to individuate the senses). Then, there was a debate over whether the concepts of commonsense psychology, such as or, should be treated as theoretical posits, and hence open to significant revision or elimination, or whether they were instead the targets of explanation. I will argue that an eliminativist approach to has significant merit. (shrink)

An introduction to section two, which introduces and summarises two recent critiques of belief in conspiracy theories by social scientists, as well as introducing the various arguments in the section.

Many millions of people hold conspiracy theories; they believe that powerful people have worked together in order to withhold the truth about some important practice or some terrible event. A recent example is the belief, widespread in some parts of the world, that the attacks of 9/11 were carried out not by Al Qaeda, but by Israel or the United States. Those who subscribe to conspiracy theories may create serious risks, including risks of violence, and the existence of such theories (...) raises significant challenges for policy and law. The first challenge is to understand the mechanisms by which conspiracy theories prosper; the second challenge is to understand how such theories might be undermined. Such theories typically spread as a result of identifiable cognitive blunders, operating in conjunction with informational and reputational influences. A distinctive feature of conspiracy theories is their self-sealing quality. Conspiracy theorists are not likely to be persuaded by an attempt to dispel their theories; they may even characterize that very attempt as further proof of the conspiracy. Because those who hold conspiracy theories typically suffer from a crippled epistemology, in accordance with which it is rational to hold such theories, the best response consists in cognitive infiltration of extremist groups. Various policy dilemmas, such as the question whether it is better for government to rebut conspiracy theories or to ignore them, are explored in this light. (shrink)

In this concluding chapter Dentith presents a synthesis of the views on offer, arguing that the various philosophical, sociological and psychology theses defended in this section point towards a necessary reorientation of the literature, one which requires we purge public discourse of the pejorative aspects of the terms ‘conspiracy theory’ and ‘conspiracy theorist’ and, rather, engage with conspiracy theories as theories (like we do with theories in the Sciences and the Social Sciences) appraising them on their particular merits. Not just (...) that, but there is even room in our discourse to celebrate and promote conspiracy theorising (as we do theorising in other domains) given the need to be ever vigilant with respect to the existence of conspiracies in our polities. Sometimes, Dentith argues, that even requires that we treat some on-the-face-of-it ridiculous conspiracy theories seriously and ask how and who should investigate them. (shrink)
